Title: Improvements in resilient connections for reciprocating elements such as percussion hammer heads and valves
IPC: B25D17/06
Filed: 1953-02-23
Abstract: 730,420. Valve accessories. BOSCH GES., R. Feb. 23, 1953 [Feb. 23, 1952], No. 4929/53. Class 135. [Also in Groups XXIII and XXXII] In a resilient connection for controlling the operation of a reciprocating element, the longitudinal axis of a spring 12 is curved so that one or more of the convolutions engage with initial pressure when the spring is at rest, against the'sides of a surrounding sleeve or casing 1. As shown, applied to a percussion hammer, a connecting- rod 3 (driven by means not shown) carries a member 2 slidable in the casing 1, and a bush 4 of a vibration-damping plastic material. The bush 4 has a helical groove on which the end of the spring 6 is threaded. The other end of the spring 6 is threaded at 9 on an extension 8 of a hammer head 7 which impacts against a tool (not shown). The transverse movement of the spring in a widened endportion of the thread 9 results in a further degree of vibration damping. The ends of the spring may alternatively be disposed coaxially with the arcuate axis of the curved spring. As applied to valve springs, a plurality of springs may be mounted in a casing with an individual casing surrounding each spring.

Abstract: 907,189. Ferro-resonant circuits. BROOKHIRST IGRANIC Ltd. April 13, 1959 [Feb. 13, 1959], No. 5001/59. Class 40 (9). A series ferro-resonant circuit comprising a linear capacitor C and a saturable inductor S is triggered from a low to a high current state by movement of a permanent magnet towards the inductor or by relative movement between the permanent magnet and a magnetic shunt. The direction of movement is reversed to restore the current to its initial value, the extent of movement necessary being reduced by short-circuiting the capacitor through a transistor t. The ferro-resonant circuit may be energized from a 2 kc/s. supply, and a half-wave rectified output derived from the capacitor which is periodically short-circuited by a 50 c/s. supply applied to the transistor base by way of a saturating transformer T. The short-circuiting equipment may be common to a number of ferro-resonant circuits connected to terminals t<SP>2</SP>, t<SP>3</SP>.

Title: Improvements in or relating to miners lamps and the like
IPC: F21L23/00
Filed: 1923-02-21
Abstract: 214,777. Hallsworth, H. Feb. 21. 1923. Miners' and like safety lamps are provided with a thermostatic device influenced by increase in temperature of the combustion products when methane is present and adapted to indicate on a scale or dial the percentage of such gas in the atmosphere. Provision is made for bye-passing the combustion products with respect to the thermostatic device so as to expedite the return of the indicator to zero after a test has been made. The device comprises a spiral bimetallic strip h anchored at one end to a casing g and operating through a train of gear-wheels g<3> - - g<6>, a pointer g' moving over a scale calibrated in percentages of methane present. The casing g is so arranged on the lamp casing f that the strip h is influenced by combustion products escaping through a port e<2> in the side of the bonnet e. The port e<2> is controlled by a valve l sliding in guides on the bonnet e and interconnected with a valve i, controlling a port e<1> in the top of the bonnet, by a rod k, pivoted link j and an operating rod i<1>. Normally the valve i is maintained closed by a spring i<3> and the combustion products impinge on the thermostatic device but when, after making a test, a quick return of the pointer to zero is required the valve i is opened by means of the rod i<1>, thereby closing the port e<2>, the combustion products then escaping out of the top of the bonnet.

Title: Process for separating carbon monoxide and olefines from gaseous mixtures
IPC: C01B32/40
Filed: 1958-02-17
Abstract: Carbon monoxide and one or more olefins may be absorbed in and desorbed from an aqueous solution of mono- and di-valent copper, 5-20%, preferably 10-15% of the copper being in the bivalent form. The gases may be absorbed from a gaseous mixture obtained by the thermal splitting of hydrocarbons.  The absorbent solution may be neutral, or may contain free hydrochrolic acid, ammonia, an amine, or a hydroxyalkylamine, e.g. monoethanolamine.  It may be prepared by heating a mixture of cuprous oxide, ammonium nitrate, mono-ethanolamine, and water, driving off the ammonia set free, and partially oxidizing the resulting cuprous solution.  The cuprous solution may alternatively be prepared by interacting cuprous oxide and aqueous nitric acid in the presence of monoethanolamine, or by dissolving copper in an aqueous ammoniacal ammonium salt solution in the presence of air or oxygen. Carbonate, chloride, acetate, or formate ions may be present instead of nitrate ions.  The cuprous solution may be oxidized with air or oxygen at a temperature of 30 DEG -70 DEG C. and under a gauge pressure of 0-50 atmos.  Absorption may be effected at a temperature of 0 DEG -30 DEG C. preferably 0 DEG -20 DEG C., and a gauge pressure of 1-50 atmos., preferably 10-30 atmos.  Desorption may be effected at a temperature of 30 DEG -70 DEG C., preferably 40 DEG -60 DEG C., and under an absolute pressure of 0,1-2 atmos.  The desorbed solution may be recycled to the absorption step.  Partial reduction of the absorbent solution may be allowed to take place, the solution being reoxidized between the steps of desorption and recycling.  Alternatively, partial reduction may be prevented by carrying out the absorption in the presence of oxygen.

Abstract: 789,776. Feeding webs. ROBERTSON, J. D. Feb. 20, 1956 [June 29, 1955], No. 5224/56. Class 100(1) An apparatus for accumulating web material 13 comprises a pivotally supported receptacle 38 having an inclined wall 40, web-feeding means associated with the receptacle for feeding the material into the receptacle, and mechanism connected to the receptacle for tilting the receptacle about its pivot to change the degree of inclination of the wall 40. As shown the web material 13 is unwound from a supply roll 12 by feed rollers 37, 37<SP>1</SP>, mounted adjacent the receptacle 38. The feed rollers 37, 37<SP>1</SP> maintain an accumulation of web material within the receptacle, so that the material may be withdrawn continuously for processing. A control device may control the operation of the feed rollers in response to a predetermined depletion of material in the receptacle. The wall 40 is pivotally mounted on a rod 42 extending between frame members 18. The lower end portion of the wall 40 is curved upwardly at 41 to form folds in the material. A cable 66 is connected to a lug 68 on the receptacle, while a similar cable, not shown, is attached to a lug on the opposite side of the receptacle, both cables being guided by pulleys and wound around a drum 78 of a winch driven by a handle 90, such that the inclination of the wall 40 may be adjusted to suit varying conditions, e.g. the type of material being accumulated without interrupting the feed. Guide bars 92 comprising telescopic portions 92a, 92b are adjustable transversely of bars 96, 98. Thus, the positions of the bars may be adjusted to effect guiding of webs of various widths. When the inclination of the wall 40 is varied, the bars 92 pivot about the bar 96, the bars increasing or decreasing in length as required. Material is withdrawn from the receptacle around a guide roller 46 and tensioning rollers 54, 56, and 60.

[Class 32] In evaporators having tubular units heated externally by desuperheated steam, the steam is desuperheated by contact with a spray of condensate produced in the evaporator and pumped into contact with the superheated steam by an injector operated by the superheated steam. Vapours derived by the evaporation may be circulated in admixture with the steam as heating agent, this circulation being so effected by injector action of the steam. The tubes of an evaporator d are heated by superheated steam from a supply line a passing through the desuperheater c divided by a baffle c'. Condensate produced in the evaporator and in the desuperheater is collected in U tubes e and circulated through a pipe g' by the injector action of steam tapped off through line h<SP>1</SP> and passed through an injector h the condensate issuing through a spray head g in the path of the superheated steam which is thus desuperheated.
